The idea behind this image is actually something for a story I’m writing… or attempting to.
It revolves around the idea that a long time ago when Queens family first moved to there new country, a group of Nightmare Moon Cultists followed with to escape the law of Nightmare Worship.
So they used a ritual to get a moon dripping to get closer to there ‘Savior’ Nightmare Moon, a liquid dripping from the moon that gave them hallucinations, a drunken stupor and several other effects if taken excessively. However in mares it had a side effect… pure drippings would cause them to not only experience hallucinations But start to grow larger breasts and lactate a strange liquid.
This liquid was a diluted form of the drippings, removing all traces of the narcotic that it was- and the side effects. It had become a wine- a sweet liquid that they kept on hand. The mares who were affected… swelled to the point many cultists refereed to them as barrels.
And when the current Sizere family line of the time caught wind of this ‘wine’- they decided to make it one of there exports back to Equestria.
Never once did they question where it came from, only that they keep making it.
Fast forward several generations and Queen Size and her family get a notification from an Equestrian Government official that there have been strange reports on there shipment stock. Barrels… when they only produced bottles. So… Queen decides to investigate the Vineyard and the family who runs it in the current era.
And of course… gets into a bit of trouble herself.

Not going to spoil how it ends… I’ll leave that for when I actually finish it~
